POSCO Argentina S.A.U. is the Argentine subsidiary of South Korea's POSCO Holdings, a multinational steel and materials conglomerate. Established in 2018, the company focuses on lithium extraction and processing from brine deposits in the Salar del Hombre Muerto, spanning Salta and Catamarca provinces.
It operates the Sal de Oro project, featuring a Phase 1 lithium hydroxide plant in General Güemes Industrial Park, Salta, with an annual capacity of 25,000 tons—sufficient for batteries in approximately 600,000 electric vehicles. The facility, inaugurated in late 2024, is currently ramping up production. Phase 2 involves a lithium carbonate plant slated for completion in late 2026, enhancing output and diversification.
With offices in Salta and Catamarca, POSCO Argentina recently expanded by acquiring the adjacent Hombre Muerto North lithium brine project in April 2026, securing additional resources estimated at 1.58 million tons of lithium. The company employs direct lithium extraction technology developed by its parent, supporting POSCO's battery materials supply chain.
